The Gun Metal spray is the latest installment in the successful line of Colour Primers from The Army Painter. The Gun Metal is a rich and dark metal and is nothing but the perfect basecoat for Knights and dark Sci-Fi & Fantasy. Especially vehicles will benefit tremendously from this spray – and a worn and battle scarred look is easily achieved by applying Warpaints colours onto the matt surface. We recommend Quickshade Dark Tone or the Warpaints Dark Tone Wash for the perfect shading.ng look.
